dts-gen

[StreetStrider]

I remember some people working on this. Check google, dts-generator, dts-bundle-generator, dts-gen is it what you're looking for?

Thanks but none of these are equivalent. dts-gen is solving a completely different problem, dts-generator doesn't do sourcemaps, and dts-bundle-generator operates on a single entry point

and dts-bundle-generator operates on a single entry point

Technically it works on multiple entries too, but you'd probably mean here that it doesn't extract common chunks out of entries (and sourcemaps problem is applicable too).
